​Let's find Surface Area Using a Net.

• Recall that the surface area of a polyhedron is the total area of all the faces.

Open Ended

What is the surface area of this Polyhedron? Remember to use your formulas for each shape and then add to get surface area.

Triangle- 1/2 B x H

​Let's practice unfolding into a net and finding surface area.

​Let's do one more together.
What is the surface area in square units of Polyhedron ?

Draw

Label each face of the rectangular prism with its area. Then, write the total surface area of the polyhedron.

Draw

Jada drew a net for a triangular prism and calculated its surface area. However, she calculated the areas of the right triangular faces incorrectly. Fix Jada's mistakes and then find the surface area.
